Electronic Boost Controllers?

Hey fellas,

Had may car in for a tune recently and was told my boost controller wasn't working. (one of the earlier model HKS EVC's).

So obviously I'm looking to get one back in ASAP and was wondering what's the way to go in ways of value/quality without going full on overkill.

In a brief look through the forums I've heard good things about the G-Reddy Profec B Spec II.

Any +1's or opinions on that, or other option would be much appreciated.

Thanks in advance.

Thanks guys, I'll have a look at these links, from forum opinion the G-Reddy Profec B Spec II seems to be the way to go haven't heard a bad word against it, so I'll look into getting myself one.

Thanks again.

Is this too good to be true?

G-Reddy Profec B Spec II - eBay

I would normally never consider buying anything for my car off eBay, but i thought I'd check.

Money's not the issue, but if given the chance I'd think we'd all like to keep some of what we earn.

hey mate,

got my spec 2 from performance wise, they are on the forums here. after my payment cleared it took two days to get to me (from japan too). trackable post and awesome price i cannot reccomend them strongly enough!

I just bought a Gizzmo ms-ibc.. supposedly the goods after doing a bit of searching on this forum.

The world's fastest gts-t runs the same controller, so i thought why not :P

Anyways, mine gets installed and tuned on saturday. Car already has a boost controller but a crappy one so basically looking for boost ramp rate improvements not peak power (which i expect to remain unchaged as it will still run the same boost).

Apexi AVC-R anyone? Ive got one and i find it to be pretty damn cool,.. even better when u know how to use everything on it :thumbsup:

Pricey but got some pretty cool features, cant remember all the shit it can do so i copied this off RHD

Description APEXi AVC-R Boost Controller. This can be used on virtually all turbo vehicles.

Here is what Apexi has to say about their product:

The AVC-R is a digital boost controller that allows the user to modify the boost pressure level on turbocharged vehicles. While there are many boost controllers on the market, none of the other includes as many features as the AVC-R, period. Despite all of the complex features included the unit, the AVC-R is flexible enough to be used by beginners. Entry level users need only to input a desired boost level and the AVC-R's trademark self learning CPU processor does the rest.

The AVC-R also uses a highly durable, fast action solenoid valve to physically control the boost . The valve movement (Boost Duty Cycle) can also be modified. Raising the duty cycle increases boost response, while lowering the duty cycle will slow boost response. This feature allows boost response adjustment for varying turbo sizes. Since larger turbos take longer to spool up ( bad low end response) the duty cycle should be raised under lower RPM's for better response. The opposite should be done for smaller turbo's ( excellent low - mid range response, but limited top end power.) A'PEXi engineers address this issue by including extra menus for RPM based boost control. Drag racers may want to utilize the Gear based boost control function. Aside from the basic functions above, the AVC-R has a Start Duty Setting (allows the boost to momentarily overshoot according to gear).

The AVC-R also includes a Scramble Boost function which allows the user to momentarily raise or lower the boost level at the push of a button. Raising the boost level is commonly used when an extra burst of power is needed (ex. entering a freeway). This feature can also be used in drag racing. The driver can set the main boost level to a low setting for maximum traction then, once full traction is achieved, the scramble boost can allow the vehicle to boost full power.

The AVC-R displays data in three different modes: Numerical, Analog, and Graph. Numerical Mode allows the user to monitor up to four different parameters in numbers and also shows peak hold values on demand. The Analog Mode displays up to two values in an easy to read meter style display. Peak Hold is also included in this function. The Graph Mode offers real time graph plotting with a Ghost map trace feature built in. The graph can replay movement up to 60 seconds.

Unfortunately the apexi avc-r has no gain setting i don't think...losing precious boost ramp rate.

This is the reason i just purchased the gizzmo.. so i can ditch the PFC boost controller kit.

Several years ago dirt_garage did some testing and found switching from the avc-r to a blitz dual solenoid found gains even when running same boost pressure.

The amount of info it can display is handy though!

      Old Son, did you re-use the Holden ABS in the new shell or try a different module?

      Another little story of weird shit happening

      By GTSBoy · Posted

      Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.

      Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up

      Does anyone know ow what these two plugs are for and if they should be unplugged? Just put the dash back together and can't remember if these were plugged in before or unplugged! (Blue and white plugs) 🤦🏽‍♂️

      Looking for a part number for this part here

      By dbm7 · Posted

      Did some FASTing ...got the impression that the actual part# was a moot point ; seems all of these hardlines for coolant are discontinued/NLA... like, I take it you're after the hardline that bolts onto to the manifold...that's NLA according to amayama & nengun .... ...just to clear up some confusion, they typically mounted the AAC valve to the intake manifold somewhere near a coolant passage, so the body of the valve heats up & holds it open when engine's up to temp - no coolant flows through the valve, it's a mechanical, thermal connection.
